Description

Technical Field

[0001] This application relates to the field of motor technology, and in particular to a motor water-cooling structure with internal and external double water channels. Background Technology

[0002] In the process of motor technology innovation, motors continue to move towards flatter, smaller, and higher-power designs. This trend has significantly improved the energy density of motors; however, the resulting heat dissipation problem has become increasingly prominent. Conventional heat dissipation solutions are insufficient to effectively cope with the large amount of heat generated by motors operating at high power in confined spaces, causing performance degradation due to overheating and making it difficult to maintain stable output power at the expected level.

[0003] The inner side of the stator coil and the outer side of the rotor are the main heat-generating areas of the motor, and existing cooling technologies cannot adequately cool them. Traditional single-channel cooling systems can only dissipate heat from a specific part of the motor, resulting in a single heat dissipation path and low heat dissipation efficiency, making it difficult to meet the heat dissipation requirements of the motor under high load operation.

[0007] The mounting base is connected to the front cover and extends into the base. The mounting base has a third water channel on its body.

[0008] Coolant enters the inlet of the first water channel from the inlet, and flows along the first water channel to cool the base. Coolant enters the second water channel from the outlet of the first water channel, and flows along the second water channel to cool the front cover. Coolant enters the third water channel from the outlet of the second water channel, and flows along the third water channel to cool the interior of the base.

[0035] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0036] An embodiment of this application provides a motor water-cooling structure with internal and external dual water channels, such as... Figures 1-7 As shown, it includes a base 1, a front cover 5, and a mounting base 7.

[0037] The base 1 has a water inlet 2 and a water outlet 3, and the base body of the base 1 is provided with a first water channel 4 communicating with the water inlet 2. The base 1 is the basic support component of the motor and is used to install other components of the motor.

[0038] The front cover 5 is connected to one end of the base 1, and a second water channel 6 is provided on the cover body of the front cover 5. The front cover 5 is used to seal and protect the inside of the motor.

[0039] The mounting base 7 is connected to the front cover 5 and extends into the base 1. The mounting base 7 has a third water channel 8 on its body.

[0040] Coolant enters the inlet of the first water channel 4 through the inlet 2, flowing along the first water channel 4 to cool the base 1. The coolant then flows through the outlet of the first water channel 4 into the second water channel 6, flowing along the second water channel 6 to cool the front cover 5. Finally, the coolant flows through the outlet of the second water channel 6 into the third water channel 8, flowing along the third water channel 8 to cool the interior of the base 1. The coolant is a liquid, such as water or a specific coolant, used to remove heat generated by the motor.

[0041] In this embodiment, the coolant enters the inlet end of the first water channel 4 from the inlet 2 of the base 1, flows along the first water channel 4 to cool the base 1, then enters the second water channel 6 of the front cover 5 through the outlet end of the first water channel 4, flows in the second water channel 6 to cool the front cover 5, then enters the third water channel 8 of the mounting base 7 through the outlet end of the second water channel 6, flows in the third water channel 8 to cool the components inside the base 1 (such as stator, rotor, etc.), and finally flows out from the outlet 3 of the base 1.

[0042] In some high-power electric motors, this dual-channel water-cooling structure is used. The coolant is pumped in from the inlet 2 and passes through each channel to cool different parts of the motor, effectively reducing the temperature of the motor during operation.

[0043] This application improves the heat dissipation efficiency of the motor by setting up internal and external dual water channels to cool the base 1, front cover 5 and components inside the base 1 respectively. This can effectively reduce the operating temperature of the motor, extend the service life of the motor, and improve the reliability and stability of the motor.

[0044] In one embodiment, such as Figure 3 and Figure 4 As shown, the first waterway 4 includes a first annular segment 41 and a second annular segment 42 that are parallel to each other. The first annular segment 41 and the second annular segment 42 are both arranged along the circumferential direction of the base 1. One end of the first annular segment 41 is connected to the water inlet 2, and the other end is connected to one end of the second annular segment 42.

[0045] In this embodiment, the first annular segment 41 and the second annular segment 42 are arranged around the base 1, that is, they are arranged around the base 1, so that the coolant can circulate around the outer periphery of the base 1, increasing the contact area between the coolant and the base 1 and improving the cooling effect.

[0046] In use, the coolant enters the first annular section 41 from the inlet 2, flows along the first annular section 41, enters the second annular section 42 from the other end, continues to flow along the second annular section 42, and then flows out from the other end of the second annular section 42 into the second water channel 6.

[0047] The first water channel 4 of this application adopts a parallel annular segment structure, which increases the flow path of the coolant in the base 1 and the contact area with the base 1, improves the cooling efficiency of the base 1, and can better remove the heat generated by the base 1.

[0048] In one embodiment, such as Figure 6 and Figure 7As shown, the second waterway 6 includes a first vertical section 61, a second vertical section 62, and a third annular section 63. One end of the first vertical section 61 is connected to the other end of the second annular section 42, and the other end is connected to one end of the third annular section 63. The third annular section 63 is arranged along the circumferential direction of the front end cover 5.

[0049] In this embodiment, after the coolant cools the base 1 in the first water channel 4, it flows out from the other end of the second annular section 42. Since one end of the first vertical section 61 is connected to the other end of the second annular section 42, the coolant flows into the first vertical section 61. Then, the coolant flows along the first vertical section 61 to its other end and enters the third annular section 63 connected thereto. In the third annular section 63, the coolant flows around the front cover 5 circumferentially, making full contact with the front cover 5 during this process, absorbing the heat generated by the front cover 5, and thus cooling the front cover 5.

[0050] This application introduces coolant from the base 1 into the third annular section 63 of the front cover 5 via the first vertical section 61, ensuring that the coolant can smoothly enter the cooling channel of the front cover 5. The third annular section 63 is arranged circumferentially around the front cover 5, so that the coolant can cool the front cover 5 evenly, avoid local overheating of the front cover 5, and improve the heat dissipation effect of the front cover 5.

[0051] In one embodiment, a first seal is provided between the water inlet end of the second waterway 6 and the other end of the second annular segment 42.

[0052] In this embodiment, the first seal is used to seal the gap between the inlet end of the second water channel 6 and the other end of the second annular section 42 to prevent coolant leakage. During the process of coolant flowing from the second annular section 42 into the second water channel 6, the first seal ensures the sealing of the connection, allowing the coolant to flow only through the designed channel.

[0053] The first sealing element provided in this application can effectively prevent coolant leakage, ensure that the coolant flows along a predetermined path, improve the reliability and cooling effect of the water cooling system, and avoid damage to the motor caused by coolant leakage.

[0054] In one embodiment, such as Figure 2 and Figure 4 As shown, the mounting base 7 has a ring structure, and one end of the mounting base 7 that extends into the machine base 1 is located between the inner side of the stator and the outer side of the rotor.

[0055] In this embodiment, the mounting base 7 is annular in shape and can be made of metal. The stator is the stationary part of the motor, typically consisting of an iron core and windings. The rotor is the rotating part of the motor, rotating in the magnetic field generated by the stator.

[0056] In use, the mounting base 7 extends into the machine base 1 in a ring structure, located between the inner side of the stator and the outer side of the rotor. The coolant flows in the third water channel 8 of the mounting base 7 to cool the area between the stator and the rotor.

[0057] The mounting base 7 of this application is located between the inner side of the stator and the outer side of the rotor. The third water channel 8 can directly cool the key heat-generating components (stator and rotor) inside the motor, which improves the heat dissipation efficiency inside the motor and can better ensure the normal operation and performance of the motor.

[0058] In one embodiment, such as Figure 4 As shown, the third waterway 8 has a serpentine structure and is arranged along the circumferential direction of the mounting base 7. The water inlet of the third waterway 8 is connected to the other end of the third annular section 63, the water outlet of the third waterway 8 is connected to one end of the second vertical section 62, and the other end of the second vertical section 62 is connected to the water outlet 3.

[0059] In this embodiment, the serpentine structure is curved and resembles a snake, exhibiting a continuous, winding shape. This shape allows the third water channel 8 to have more bends and detours, increasing the flow path length of the coolant within it. Furthermore, the third water channel 8 is arranged around the mounting base 7.

[0060] During operation, the coolant cools the front cover 5 in the third annular section 63 of the second water channel 6, and then flows out from the other end of the third annular section 63. Because the inlet of the third water channel 8 is connected to the other end of the third annular section 63, the coolant flows into the third water channel 8. In the third water channel 8, which has a serpentine structure and is arranged circumferentially along the mounting base 7, the coolant meanders, making full contact with the components around the mounting base 7 (such as the area between the stator and rotor), absorbing the heat generated inside the base 1, and cooling the interior of the base 1. After flowing out from the outlet of the third water channel 8, the coolant enters the second vertical section 62 connected to it, then flows along the second vertical section 62 to its other end, and finally flows out of the motor from the outlet 3 connected to the other end of the second vertical section 62.

[0061] This application increases the flow path of the coolant inside the base 1 and the contact area with the heat-generating components through the serpentine structure of the third water channel 8, which can more effectively absorb the heat inside the base 1 and improve the cooling efficiency of the base 1. Furthermore, by connecting the outlet of the third water channel 8 to the second vertical section 62, and then connecting the second vertical section 62 to the outlet 3, the circulation path of the coolant is made more reasonable, ensuring that the coolant can be smoothly discharged from the motor to complete the entire cooling cycle.

[0062] In one embodiment, the mounting base 7 and the front cover 5 are detachably connected, for example, by bolts. When maintenance or repair of the motor's internal components is required, the mounting base 7 can be removed from the front cover 5 for easy operation; during installation, the mounting base 7 is then reconnected to the front cover 5. This facilitates maintenance, repair, and component replacement of the motor's internal components, improving the motor's maintainability and reducing maintenance costs and difficulty.

[0063] In one embodiment, a second sealing element is provided between the inlet end of the third waterway 8 and the outlet end of the second waterway 6, and between the outlet end of the third waterway 8 and the outlet 3.

[0064] In this embodiment, the second seal is used to seal the gap between the inlet end of the third water channel 8 and the outlet end of the second water channel 6, as well as between the outlet end of the third water channel 8 and the outlet 3, to prevent coolant leakage.

[0065] During the process of coolant flowing from the second channel 6 into the third channel 8 and from the third channel 8 out to the outlet 3, the second seal ensures the sealing of the connection, so that the coolant can only flow through the designed channel.

[0066] The second seal provided in this application can effectively prevent coolant leakage at the connection between the third water channel 8 and the second water channel 6, and between the third water channel 8 and the outlet 3, ensuring that the coolant flows along the predetermined path, improving the reliability and cooling effect of the water cooling system, and avoiding damage to the motor caused by coolant leakage.

[0067] In summary, when applying this application, if Figure 8 As shown, coolant is pumped into the inlet of the first water channel 4 from the inlet 2 of the base 1 by a power device such as a water pump. The coolant first enters the first annular section 41 and flows around the base 1 along the first annular section 41. During this process, the coolant comes into full contact with the base 1, absorbing the heat generated by the base 1 and achieving initial cooling of the base 1. Afterward, the coolant flows from the other end of the first annular section 41 into the second annular section 42, and continues to flow around the base 1 in the second annular section 42, further carrying away the heat from the base 1.

[0068] After flowing out from the other end of the second annular section 42, the coolant passes through the joint sealed by the first seal and enters the second water channel 6 of the front cover 5. The coolant flows around the front cover 5 in the second water channel 6, evenly absorbing the heat generated by the front cover 5 and cooling the front cover 5.

[0069] After the coolant flows out from the outlet of the second water channel 6, it passes through the connection sealed by the second seal and enters the third water channel 8 of the mounting base 7. The third water channel 8 has a serpentine structure, in which the coolant meanders and flows, increasing the contact area and flow path with the internal components of the base 1 (such as the stator and rotor), fully absorbing the heat generated inside the base 1, and efficiently cooling the inside of the base 1.

[0070] After the coolant has cooled the interior of the base 1 in the third water channel 8, it flows out from the outlet of the third water channel 8, passes through the connection sealed by another second seal, and finally flows out from the outlet 3 of the base 1. The outflowing coolant can be cooled by a cooling device (such as a radiator) and then recirculated into the inlet 2 of the base 1 to continue the cooling process.

[0071] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
